HORSESHOE-MACHINE.

ESPECIFICATION forming part of Letters Patent No. 328,461, dated October 2f], 1885.

Application filed December 26, 1884. Serial No. 151,134. (No model.)

To aZZ whom it may concern:

Be it known that I, LOUIS G. CLAUDE, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Horseshoe-Machines, of which the following is a specification.

This invention relates to machines for finishing horseshoes, its principal object being to provide means for forming undercut creases in a bent shoe. Heretofore machine-made horseshoes have been creased with undercut creases in the bar before bending; or they have been creased with simple creases, not undercut, after being bent. My improved machine is the first, so far as I am aware, which enables a bent shoe to be creased with undercut creases. My machine not only creases the shoe, but also at the same operation forces the heels inward and squeezes the shoes to the desired outline against a former, presses them flatwise, forming the concave, if desired, and strikes up the toe-clip. It is, as I be-" lieve, the first machine which both creases the shoe and strikes up its toe-clip at one operation.

Figure 1 of the accompanying drawings is a front elevation of my machine, it being shown in the position for feeding on the shoe to be acted upon; Fig. 2 is a vertical mid.-. section cut on the line 2 2 in Fig. 1, showing the machine in the same position. Fig. 3 is a plan, partly in horizontal section, on the line 3 3 in Figs. 1 and 2, showing the machine in the position occupied while the shoe is being creased. Fig. 4 is an enlarged fragmentary vertical section cut on the line 4 4 in Fig. 3, showing the working parts during the creasing operation. Fig. 5 is a section on the same plane as Fig. 2, showing the'working parts in the position of striking up the toe-clip. Fig. 6 is a face view of one of the creasers. Figs. 7 and 8 are cross-sections thereof cut, respectively, on the lines 7 7 and 8 8 in Fig. 6; and Fig. 9 is a cross-section of the horseshoe with the crease formed by the portion of the creaser shown in Fig. 7. I

Let A A denote the fixed frame of the machine, affording suitable bearings for the rotary shafts; B, the main shaft; 0 C, the creasershafts; D, the driving-shaft, and E the cliprper-shaft. The driving-shaft D bears a pinion, d, which meshes with a gear, b, on the main shaft, whereby the machine is driven. Power may, however, be applied directly to the main shaft, omitting the shaft D and gears d b. The shafts O O are driven from the shaft B, and at the same speed, by miter-gears c c. The shaft E is driven from the shaft B, and at a speed three times greater, through a gear, a, on shaft B, and a pinion, e, on shaft E.

The shaft B is enlarged between the flanges A A, and on one side it is extended laterally and flattened, forminga table, F, which carries jaws for the reception of the horseshoe. On the center of this table is fixed an anvil or former, G, which has a plane face around it, on which to lay the shoe, and a raised center, 9, the outline of which is the same as the inner outline of the finished shoe.

At each side of the anvil G is a jaw, H, each jaw having an outline coinciding with that of the exterior sides of the finished shoe. The jaws H are formed on or fixed to slides I I, which move longitudinally of the shaft B, being confined in undercut or dovetail slideways in the table F. Each slide I bears a roller,j, which rolls against an annular track, J, fixed to the frame A, and the slide is pressed toward the side, thereby keeping the roller 7' in contact with its track, by a spring, 2', as best shown in Fig. 4. The jaws are shown wide open in Fig.1 in the position for feeding on the shoe. As the shaft B revolves, carrying the shoe and jaws upward, the rollers jj 8 5 encounter inclines h h on the tracks J J, and by these inclines the slides I I and jaws H H are forced together, closing the jaws powerfully against the sides of the shoe, and thereby pressing the shoe against the projecting 9o center 9 of the anvil. By this operation the heels of' the shoe are forced together to the desired form, the shoe is given the correct outline, and its outer and inner edges are smoothed and finished. Before the shaft has 5 I IOO act upon the shoe at an angle, as best shown in Fig. 4.. Each roll K has four creasers, k k,-

formed on it, about ninety degrees apart,with intervening recesses Z Z. Fig. 6 is a face view of one of these creasers with the surrounding pressing-face m from which it projects. Each creaser consists of a projecting rib of nearly V shape in transverse section,with four (more or less) points or teeth for indenting the nailholes. At the toe end of the shoe the creaser projects with its inner side parallel to the general plane of the creasing-roll, as shown in cross-section, Fig. 7, whereby it is adapted to form an undercut crease in the shoe, as shown in Fig. 4. A section of one leg of the shoe is shown on a larger scale in Fig. 9, illustrating the manner of driving the nail at the toe of the shoe at an angle corresponding to the incline of the hoof, as determined by the undercutting of the crease. The heel portion of the creaser is beveled off on the inner side to form the crease without undercutting. This portion of the creaser is shown in section in Fig. 8.

As the shoe is carried over the top of the shaft B it is engaged by the two creasing-rolls KK, the smooth face an on each roll pressing down on the flat under face of the shoe, and the creasers k k indenting the creases in the shoe. Only one of the creasers k on each roll K acts upon the shoes, the others revolving idly until the first is worn out, when the roll is turned one quarter around on its shaft, thereby bringing the next into use, and so on, using the four creasers thus successively until all are worn out, when the roll is replaced by a new one. To enable this turning and readjustment of the roll to be readily effected, the roll has four key-ways formed in it, either of which can be turned to coincide with the keyway in the shaft, or the shaft may have a squared end. The recesses Z Z on the creasing-rolls are to permit the passage of the projecting corners an of the table F, as shown in which strikes up its toe-clip.

Fig. 5. I

After the shoe has passed over the top of the shaft B and there received its creases, it is still held by the jaws H H, and in turning downward it encounters the clipper-roll L, This roll is borne between arms p on the shaft E. This shaft is timed to rotate relatively to the shaft B in such manner that the roll L encounters and wipes past the toe end of the shoe as the latter passes down on the rear side of the shaft B. The shoe is formed, by preference, with a slight projection at its toe, (seen in the shoe shown in Fig. 3,) and this projection is struck by the roller and wiped or swaged up, receiving its form between the wall of the anvil G and the face of the roller L. This operation is clearly shown in Fig. 5. .As the roller L advances, after thus having formed the toe-clip, it enters a recess, q, in the table F, and passes through this recess in advance of the table, thus, by its more rapid movement, getting out of the way of the shoe and table. By the time it has reached this position on its next revolution the table F has passed below it. The clipper-roll L makes two idle revolutions between each clipping operation, on each third revolution encount: ering the shoe and striking up the toe-clip thereon. The shoe, in continuing its revolution is next released by the jaws H H and dropped, falling on a trough, M, down which it slides, and whence it is conducted to the punching-press, by which its nail-holes are to be punched. The opening of the jaws H H is occasioned by the rollers j j running onto inclined portions h h on the tracks J J, whereupon the slides I I are pressed outward by their springs z 2'.

This machine finishes one shoe to each revolution of the shaft B, forcing the heels together, turning the edges of the shoe, creasing it, striking up the toe-clip, and automatically dropping it out. The shoe may also be concaved at the same operation by forming a beveled face on the anvil 0 close to its projection g, and on each side thereof, corresponding to the concave r on the shoe in Fig. 9.

This machine is equally adapted to the finishing of shoes made by bending a straight bar or to those made by stamping out a bent shoe from a plate of metal.

I am well aware thathorseshoe-machines have before been made having two rolls between which a bent shoe is passed, and by means of which it is shaped and creased, and also that machines for shaping and concaving (but not for creasing) horseshoes have been made with a reciprocating table having lateral squeezing-jaws and passing beneath a rotating die.

It is not essential that the table F in my machine shall rotate with the shoe, as it might reciprocate beneath the creases as well.

What I claim, and desire to secure by Letters Patent, is
